3D Printed Disk Sander

I’ve recently been working on a project that involves many laser cut parts that for some reason weren’t fitting very well. I was spending too much time sanding things down by hand and decided to do something about it. I printed out a disk sander attachment for my drill.

The disk sander uses a bolt as the shaft that you clamp your drill too. The bolt I used was 6/32 machine screw about 2.5 inches long. Its set through the center of the sanding disk. The head of the bolt is recessed into the disk so that the sanding plane is smooth.

Attaching the sand paper only needs a little bit of Elmers Glue-All. Just cut a disk of sand paper as close as you can get to the size of the disk.

The printer settings I used were:

Layer Height: .4mm

Infill: .4

Perimeters: 3

Top and bottom layers : 4

These settings gave me a pretty strong print which let it stand up to the drill quite well. Good luck sanding for yourself. Let me know how this worked out for you
